Whats up everyone? Last week I purchased a 1970 CJ from a friend of mine. It came with the stock drum brakes. I have read and read about doing the disc brake conversion. It seemed pretty straight forward.... Until today... I went to the scrap yard and pulled some brackets off, and calipers off an 83 k5 blazer. I got home tore into my jeep pulled the old parts off and bolted the new bracket right up. At this point I was pretty excited that this actually may be easy... So I called around and found a parts store on the other side of the metroplex that had a pair of brake rotors form a 78 CJ. I went down there and picked them up along with some new calipers. I get home all excited to bolt them up to my hubs and they don't fit!!!! My hubs appear to be stock hubs. They measure 4 1/8" inside the lugs. The rotor measures 3 5/8" on the big hole that's supposed to slide over the hub. Anybody have any suggestions on what to do? I'd hate to go down and have them machined and have some other problem with them lining up with the caliper. As far as I know it is the stock Dana 27. Any help would be most appreciated!
